"Blue" and "red" schemes had been used in the past to demonstrate "sideband asymmetry" and "squashing" in microwave devices [1]}, [2]}, [3]}; but to our knowledge fig. REF  is the first demonstration of these effects using the "green" pumping.
Furthermore, our data is acquired within a genuine single-tone scheme: there is no "cooling tone" applied to bring the NEMS mode close to its ground state, since we want to keep it classical, in strong contrast with the previous references. Note the difference in the expressions of \(T_{sa}\)  for the different schemes.
One can see that for "blue" and "red" \(T_{sa} \sim T_{noise}(2\frac{\kappa _{ext}}{\kappa _{tot}} -1 )\) , which makes it very sensitive to \(\frac{\kappa _{ext}}{\kappa _{tot}}\) 
(it even vanishes for \(\frac{\kappa _{ext}}{\kappa _{tot}}=1/2\) )
, while this is not the case for "green"; this shall be explicitly discussed in the next Section.
